WASHING MACHINE.

Application filed February 3, 1923.

To all whom it may concern.

Be it known that l, Anensrns Misoir,

a citizen of the United States, and resident of the city of New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in ashing lt'lachines, of which the following a specification.

The present invention relates to washing machines, and more particularly to that class which performs its functions by the passage of the suds through the clothes.

The invention pertains to washing machines,

employing a rotary drum containing the clothes or fabrics, which are at no time allowed to remain stationary in the water.

The main object of the invention is to provide a washing machine, having adrum, the cylindrical surface of which includes a plurality of corrugated casing-like slats, which, in the rotation of the drum, cause a circulation of water or other suitably prepared liquid, either hot or cold, and air through the clothes or fabrics in the drum, thereby cleansing or washing the same without subjecting them to the usual pounding;

rubbing, in one form of the machine, being performed by the corrugated inner faces of the slats, as the clothes are being forcibly thrown against the same in the rotation of the drum.

Another object of the invention is to produce a washing machine of the character described, which can be easily and conveniently operated, performs its functions elliciently, and which is capable of manufacture on a commercial scale, or in other words one which is not so dificult to make as to be beyond the reasonable cost of such a contrivance.

lVith these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments Serial No. 616,769.

of the invention are illustrated in the accoinpanying drawings, in which 2 Figure l is a side elevation of a washing machine constructed in accordance with the present invention; E2 is a front elevation of the drum; Fig. 3 is an end eleva tion of said drum, partly in section; Fig. lis a front elevation of a portion of one of the casing-like slats of the drum; and Fig. 5 is a transverse section taken through a few of the slats.

In the case illustrated in the drawings, the washing machine is shown as made in the form of a table, thereby serving a twofold purpose. It is obvious, however, that it may be made in any other form just as well, without departing from the invention.

lln the drawings, the numeral 10 indicates a tub, made of any suitable material, for instance of wood, and mounted upon legs 11. The cover 12 of the tub may be mounted thereon in any suitable manner, for instance hinged thereto. The tub, with its legs and cover, has the appearance of table, when the cover is in closing position.

In the ends 13 of the tub are rotatably mounted the journals 14 of a drum 15, which. may be driven in any suitable manner, for instance there may be fixed to one of the journals a pulley 16, driven by the intermediary of a belt from any suitable source of power. The drum comprises two heads 17, which are connected adjacent their peripheral portions by slats 18 and 19, made of any suitable material, for instance sheet metal. These slats are provided with a coating, protecting them from corrosion. In each of the heads of the drum is formed a suitable number of apertures 20. The slats 18 are corrugated, their longitudinal edges 21 being properly rounded and bent outwards so as not to injure the clothes or fabrics in the drum, and also for another purpose, hereinafter to be described. The slats 19 are casing-like, a clearly shown in Figs. 3 and 5 of the drawings, having each a longitudinal slot 22 in their outer walls, the width of each slot being substantially less than the width of a casing, for a purpose hereinafter to be described. The inner walls 23 of the casing-like slats 19 are corrugated and provided with two parallel rows of apertures 24 and 24', said rows being out of alignment with the slots 22 in the respective slat 19. The slats abut against the inner faces of the heads 17 of the drum and are spaced apart, thereby providing passages between the same, through which the water or other fluid is allowed to circulate. Two sets of slats are mounted alternately upon the drum heads, the slats 18 being of less width than the slats 19, their inner faces being so disposed as to form a cylindrical surface. To two diametrically oppositely disposed slats 18 are attached inwardly projecting, preferably, wooden strips 25, each having a tendency to beat and stir the clothes in the drum.

A few of the slats are connected, in a manner not shown, the connecting pieces being hinged. to the drum heads, thereby permitting the said connecting pieces and the slats thereon to be turner around. their hinges, so as to provide an opening through which the clothes or fabrics are placed into the drum. These connected slats thus provide a door, which is held in closed position by any suitable means, after the clothes or fabricsto be washed have been. placed into the drum. V

The operation of this device is as follows: Water and soap, or other washing fluids, are poured into the tub, the clothes deposited into the drum, and the door put to closing position. The drum is then rotated. In order to properly understand the operation, let us assume that first the drum rotates in the direction of the arrow shown in Fig. 5 of the drawings, and that the water level in the drum reaches the horizontal line denot ed by the numeral 26 in Fig. 1 of the drawings; The apertures 20 in the drum heads serve to equalize the fluid level inthe drum and tub. The casing-like slats, when above the water level, are, one after the other, filled with air, part of which is confined, as they are being submerged in the liquid, within those spaces of the casing-like slats that are disposed above the row of apertures 24 therein. In the further rotation of the slats, and more particularly as they reach approximately the lower dead center of the rotating drum, the air leaves the slats through the apertures 24, entering the drum and passing through the clothes or fabrics therein, the air in the slats being compressed in the rotation of the drum. As soon as the air has left the slats, streams of water issue from the said apertures, said streams also flowing through the clothes or fabrics, which are continuously kept in motion, being thrown against the corrugations on the two sets of slats and thus subjected to rubbing. Attention is called to the fact that the front and rear walls27 and 28 of the slats 19 are disposedradially, or in other words they form vanes, the front walls 27, as the drum rotates in the direction of the arrow shown in Fig. 5 of the drawings, having a tendency to cause a continuous fiow of water from thetub into the drum through the spaces between the slats and through the clothes in the drum. This flow of liquid is increased by the curved longitudinal edges 21 of the slats 18, which have also the effect of vanes, forcing the liquid against the inclined walls 27 of the slats 19.

When the'direction of rotation of the drum is reversed, air issues from the apertures 24, the radial walls 28 of the casinglike slats taking then the place of the walls 27.

From the foregoing it appears that the slats have a three-fold function, to wit: First, they serve to cause a flow of air into the drum, second they induce a flow of liquid into the drum, and, third, by reason of their corrugated inner faces they consti-- tute a washboard.

hat I claim is 1- I l. A drum for washing machines, comprising two heads, and spaced sl'atsconnecting the peripheral portions thereof, alternate slats being casing-like, having each a centrally disposed longitudinal slot in its outer wall and a single row of apertures in its inner wall on each side of theslot, all of the apertures in said inner wall being out of radial alignment with said slot and the two rows of apertures being symmetrically ar ranged in relation to said slot.

2. In a drum according to claim 1, the front and rear walls of said casing-like slats being disposed substantially radially in'relation to saidheads and the longitudinal edges of the other set of slats being bent outwards toward the peripheral portion of said head for co-operation with said radial walls.

Signed at New York, in the county of New York, and State of New York, this 28th day of December, A, D. 1922.
